Here is a neutral and interesting summary of the provided text in one paragraph: Algorithmic trading, like software development, benefits from continuous testing against historical data to ensure performance. However, collecting and processing large datasets can be a challenge. MarketStore, a platform for storing and querying financial data, offers a solution by providing a Docker-based setup that allows users to test their trading strategies quickly and efficiently. The system consists of two containers: one for the server and another for the client, which uses Python and pymarketstore to query the data. By following this tutorial, users can set up MarketStore to fetch historical Bitcoin price data from GDAX and query it using JSON-RPC, enabling them to develop and test their trading algorithms with a large dataset.
